Maddox is a self-described "kid that lived on graveyard hill." Growing up, his house was built adjacent to an old cemetery. The headstones had been moved, but unbeknownst to the Maddox family, the coffins remained underground. "When I was little my dad dug a swimming pool and hit four graves," he said, an event that caused a small uproar in the tiny town of Phoenix, OR.

Years later, Maddox combined his love of Halloween, his fascination with pulse jets, and his skills as a cabinet builder to create a coffin car. He always loved watching the Munsters, so the car is kind of an homage to the Drag-U-La coffin car that Grandpa Munster once drove. It took him about a month to build and cost around $1,300, including coffin handles he snagged off eBay.

Powered by a pulse jet – a simple, reed-like device that ignites a mixture of air and almost any kind of fuel in loud, pulsating blasts – the coffin weighs only 400 pounds and does 0-60 in nine seconds. Maddox didn't dare to go any faster. He said it was "way fun" to drive.

Unlike his other creations, which he's sold to collectors and less DIY-inclined daredevils, Maddox plans to hold on to the jet-powered coffin. Now that it's complete, we hope he'll have time to undertake other projects.
